  2. customerCHALLENGE Producing the well at maximum potential

  3. customerCHALLENGE Thick and uneven filter cakes can lead to: • Formation damage • Decreased production rates • Increased costs • Increased rig time chemical costs

  4. traditionalACID BREAKERS • Traditional acid breakers can: • Expose corrosive acids, which can lead to HSE issues • Provide uncontrolled and localized reaction • Increase the risk for wormholing • Require specialized trucks, tanks, and equipment

  5. Baroid’sSOLUTION • N-FLOWTMDelayed Action Filter Cake Breakers • Baroid’s N-FLOW breakers offer a delayed reaction, providing uniform distribution, reducing the risk of ‘hot spots’, and preventing the risk of corrosion and formation damage. • Oil and water-based filter cakes • For formations with a wide range of temperatures and pressures

  6. Applications • N-FLOWTMDelayed Action Filter Cake Breakers are highly effective in: • Horizontal wells • Openhole completions • Gravel-packed wells • Expandable screens for filter cake removal • Injector wells • Sandstone, dolomite and limestone formations • Deepwater applications • Mature well stimulation • Workover and completion

  7. N-FLOWTMFilter Cake Breaker • Neutral pH at surface • Fully-controlled, in-situ reaction • Uniform distribution for even removal • No downhole “hot spots” • Removes wormholingpotential

  8. N-FLOWTMFilter Cake Breaker • Minimal corrosion risk • Does not require special trucks, tanks or equipment • All components are environmentally acceptable • Can be mixed in the surface rig pit and pumped down-hole

  9. Filter Cake Deposition and Removal Process five two four one three After filter cake removal, the well begins to produce. Clean wellbore and prepare for filter cake removal. Deposit filter cake during drilling. Displace to wellbore fluid containing N-FLOW™breaker. Reaction takes place over the prescribed duration.

  10. Create maximum production potential by effectively removing filter cakes with N-FLOWTMbreakers BEFORE N-FLOWTM AFTER N-FLOWTM

  11. customerBENEFITS • Saferthan conventional acid breakers • Excludes harsh chemicals • Safer for workers and environment • Cost-efficient • Mixed at the surface rig pit and pumped down hole, leading to simplified operations • Effectivefilter cake removal • Fully controlled, in-situ reaction • Increase Productionquickly and efficiently by evenly removing the filter cake

  12. BAROID’S N-FLOWTM Filter Cake Breakers • Baroid’s N-FLOW™ breakers are safer than traditional acid breakers, cost efficient, and effective. Helps increase production

  13. CASE STUDY: N-FLOW™ 325 Filter Cake Breaker System Leads to Increased Production RateLocation: Kazakhstan, Mangistau Region CHALLENGE • Reducing formation damage in newly drilled 6” production intervals and in older wells during workover operations • Increasing production rates • Removing filter cake SOLUTION • BARADRIL-N® non-damaging drill-in fluid was used, providing a thin filter cake, and helping to prevent damage to the reservoir • After extensive testing, the N-FLOW™ 325 system was customized for the operator’s well conditions and proposed as the filter cake breaking system • Laboratory test results were reviewed by Baroid Global Technical Advisors and the program was implemented on 5 trial wells RESULTS • After treatment of the wells with the N-FLOW 325 system, the operator’s production department measured an increase in the productivity index • Averaged over the 5 wells, the increased production rate amounts to 86.2% improvement in produced oil volume

  14. CASE STUDY: Engineered Baroid Fluid Systems Help Operator Exceed Predicted Production Rate in Tight Sandstone ReservoirLocation: Central Saudi Arabia CHALLENGE • Minimize formation damage, and ultimately increase reservoir producibility while drilling a 1,660 ft 6 1/8-in reservoir section horizontally across sandstone formation • Logging-while-drilling data also showed a major shale body on top of the sandstone reservoir section to be drilled SOLUTION • The interval was drilled with an 8.7 lb/gal (65 pcf) INVERMUL® oil-based mud • The open hole section was then enlarged to 7-in and displaced to a customized 8.7 lb/gal (65 pcf) solids-free oil-based drill-in fluid (DIF) • A 68-bbl N-FLOW™treatment was placed inside and outside the screen using the rig pump at a rate of 250 gpm. The drillstring was then pulled to the top of the screen. After 1.5 hours, losses averaging 60 bph were observed. This indicated that the N-FLOW breaker delayed reaction had performed as planned. RESULTS • After the well was brought on production, the operator reported oil flowing immediately upon submersible pump activation at a steady productive rate, significantly exceeding offset producers performance

  15. CASE STUDY: Non-Damaging Water-Based Fluid and N-FLOW™ 408 Breaker System Lead to Maximum Production RatesLocation: United Kingdom CHALLENGE • Minimize formation damage • Optimize production through removal of filter cake without inducing losses SOLUTION • BARADRIL-N® water-based drill-in fluid system was bridged with a blend of acid soluble calcium carbonate material specifically tailored to the porosity range of the reservoir • N-FLOW™ 408 breaker was designed to remove the bridging material and filter cake • Both fluids were tested against the reservoir core to ensure compatibility and minimal formation damage RESULTS • The reservoir section was drilled successfully, ensuring minimal seepage losses and damage to the formation • The N-FLOW 408 breaker successfully removed the filter cake from the wellbore, allowing the operator to successfully test and suspend the well • After the N-FLOW 408 breaker was spotted and inhibited for 24 hours, the maximum constrained flow rate of 52 million scf per day was reached and was well within the anticipated range.
